Incidental Finding in Pre-Orthodontic Treatment Radiographs of an Aural Foreign Body: A Case Report

The presence of foreign bodies in the external auditory canal of young patients may cause, if left untreated, severe permanent damage to the adjacent anatomical structures, and infections. A 10-year-old patient with an intellectual disability underwent orthodontic evaluation. An aural radiopaque finding was visible in the lateral cephalogram and in the orthopantomography. The patient’s mother reported that her son never showed any ear discomfort, except for a mild hearing impairment that was never investigated. The patient was referred to an ear, nose and throat (ENT) specialist that removed the foreign body located in the left external auditory meatus. The careful evaluation of dental radiographs, including pre-orthodontic and interim orthodontic radiographs, may help to identify silent incidental findings that may otherwise lead to severe complications if left untreated.
